Abstract
Provided are a method for simultaneously detecting fluorescence and Raman signals for multiple fluorescence and Raman signal targets, and a medical imaging device for simultaneously detecting multiple targets using the method. The method includes: injecting at least one marker particle comprising Raman markers and receptors into the body of an animal, which can be a human; irradiating a laser beam onto the body of the animal; and detecting the optical signals emitted by the marker particle after the irradiation of the laser beam separately as fluorescence signals and Raman signals. The simultaneous detection of multiple targets may be performed even without scanning optical signals emitted by the marker particle individually with different optical fibers. As an examination may be performed by injecting surface-enhanced Raman marker particles, weak Raman signals may be augmented so as to obtain a more accurate diagnosis result in real time.
